Selile etherni kimwe cya kabiri cya emic-synthique yisumbuye ya molymer, ishowe amazi hamwe na social. Ifite ingaruka zitandukanye munganda zitandukanye. Kurugero, mubikoresho byubaka imiti, ifite ingaruka zikurikira:
① Umukozi wa Agent, ②thickener, Amashanyarazi, ④film akora umutungo,
⑤Binder
Mu nganda za chlovinel chloride, ni emulifier no gutabarwa; Mu nganda za farumasi, ni ihuriro ryibikoresho bitinda kandi bigenzurwa kandi bigenzurwa, kuko selile bifite ingaruka zitandukanye zifatika, porogaramu yacyo nayo irakomeye. Ibikurikira, nzibanda kumikoreshereze n'imikorere ya selile ether mubikoresho bitandukanye byubaka.
In latex irangi
Mu nganda za latex irangi, kugirango uhitemo HydroxyAythyl selile, ibisobanuro rusange bya violcosity ni 30000-00CPS, bihuye no kwerekana Hb250, kandi dosage yerekana muri rusange 1.5 ‰ -2 ‰ -2 ‰ -2 ‰ -2 ‰ -2 ‰ -2 ‰ -2 ‰ -2 ‰. Imikorere nyamukuru ya hydroxyyeryl mu kiraro cya latex nukujyanywa, kubuza gutaka kw'ipigi, gushinga igabanuka ry'ibipfunyika, gutuza gutanyagura pigment, hagamijwe gutura, no kongera ubuswa bw'ibice byo kubaka : HydroxyAythyl selile iraryoroshye gukoresha. Irashobora gushonga mumazi akonje cyangwa amazi ashyushye, kandi ntabwo bigira ingaruka ku gaciro ya PH. Irashobora gukoreshwa neza hagati ya PI Agaciro 2 na 12. Uburyo bwo gukoresha ni bukurikira:
1. Ongeraho mu buryo butaziguye
Ubu buryo, hydroxyAythyl ubwoko bwa selile Ubwoko bugomba gutoranywa, kandi hydroxyAyl selile hamwe nigihe cyo kuvugurura iminota irenze 30. Intambwe ni izi zikurikira: ① Shira umubare munini w'amazi meza muri kontineri ifite umuhinzi wo hejuru cyane, kandi icyarimwe ongeraho buhoro buhoro mu buryo buke, ③continue kuri stric kugeza Ibikoresho byose byurukundo cyashizwemo ④add izindi nyandiko hamwe ninyongeramusaruro, nibindi ⑤stir kugeza amatsinda yose ya hydroxyyerythy, hanyuma ongeraho ibindi bice muri formula hanyuma ugasya kugeza ibicuruzwa byarangiye.
2. Ibirimo hamwe ninzoga za Mama kugirango ukoreshe nyuma
Ubu buryo burashobora guhitamo ubwoko bwihuse, kandi bufite ingaruka zo kurwanya indwara za selile. Ibyiza byubu buryo nuko ifite guhinduka cyane kandi irashobora kongeweho ipaki ya latex. Uburyo bwo gutegura ni kimwe nintambwe ①-④.
3. Bikore muri poroji kugirango ukoreshe nyuma
Kubera ko ibiti bya kama ari bibi cyane (ibidashobora) kuri hydroxyethyyl, ibi bicuruzwa birashobora gukoreshwa mu gutegura pororge. Ibicuruzwa bikunze gukoreshwa ni amazi meza muri latex irangi, nka royone glycol, nka propylene glycol, hamwe nabakozi ba firime (nka sipilelene glycol butyl acetate). Igikori hydroxyyeryl selile irashobora kongeweho irangi. Komeza guhagurukira kugeza gushonga rwose.
In Gushyira
Muri iki gihe, mu mijyi myinshi yo mu gihugu cyanjye, qust yo kurwanya amazi n'abagenzi bacu bahanganye bahawe agaciro gakomeye n'abantu. Ikozwe na acetal reaction ya vinyl inzoga na formaldehyde. Kubwibyo, ibi bikoresho bivambuwe buhoro buhoro nabantu, kandi selile ya selile yatunganijwe ikoreshwa mugusimbuza ibi bikoresho. Nukuvuga, kubushake bwibikoresho byubaka ibidukikije, ubutugo ni ibintu byonyine.
Mu rwego rwo kurwanya amazi, igabanijwemo ubwoko bubiri: ifu yumye ipakira kandi ipakira paste. Muri ubwo bwoko bubiri bwa putty, methyl selile na hydroxypropyl methyl igomba gutorwa. Ibisobanuro byagaragaye muri rusange biri hagati ya 40000-75000CPS. Imirimo nyamukuru ya selile ni ifungwa ry'amazi, ihuza no gusiga amavuta.
Kubera ko ibiganiro byambere byabakora bitandukanye, bamwe ni calcium yijimye, calcium yoroheje, sima, na bamwe Calcium, nibindi na formulane zombi ziratandukanye. Amafaranga yongeweho ni 2 ‰ -3 ‰.
